Using HC SR04 as ultrasound microphone - Arduino Forum
2018年3月5日 · You could remove either of the transducers from the HC-SR04 and use it as an ultrasonic microphone, but that will require external amplifier circuitry to use with Arduino. You could also tap into the amplifier circuitry on the HC-SR04, shown here , but that circuit has bandpass filters to limit the frequency response (oddly enough, centered at ...
Detecting and Processing 40kHz Ultrasonic Data - Audio - Arduino Forum
2021年2月23日 · If you want to capture 40 KHz data, you need a mic that will capture at 40 KHz, and an ADC that can sample at 80KHz minimum, and 400KHz ideally for 10x sample rate. Could you start with the mic and an oscilloscope instead? The microphone only needs to cover the frequency range you wish to record.
Using 0-80 kHz ultrasonic microphone to log data onto SD card
2020年3月24日 · I've read some DIY projects for logging audio recordings to an SD card including this one: Arduino (Mega) Audio Recording: Record Audio to your Audino Mega SD card. The audio file can be played back on a standard audio application or analysed byte by byte. This Instructable will show you how audio input can be repeatedly added to a 512...
Ultrasound Listener. Electronics That Expand Your Auditory …
Electronics That Expand Your Auditory Perception. This instructable will guide you through creating a simple circuit that taps into the ultrasonic spectrum. There are tons of applications of the design, from playing the song of a dog whistle to an 'on/off' verification of ultrasound probes in medical applications.
A DIY Ultrasound Built with an Arduino - Hackster.io
Commercial ultrasound machines for medical use are extremely expensive, but Stoppi71 has a tutorial on how to build a cheap DIY version with an Arduino. To be clear, this will not yield results anywhere close to as good as you’d see from a “real” ultrasound machine .
Body-ultrasound Sonography With Arduino - Instructables
Sonography is a very important way in medicine to look inside the body. The principle is simple: A transmitter sends ultra-sonic-pulses. They spread out in the body, are being reflected by inner organs or bones and come back to the receiver. In my case I use the gauge GM100 for measuring the thickness of paint layers.
DIY ultrasonic microphone
2023年4月21日 · By building your own ultrasonic microphone, you can explore the world of ultrasonic sounds and even use it for practical purposes. With a little bit of tinkering, you can even modify it to detect higher frequencies and use it for bat detection or even for pest control. Here’s what you need to build your own ultrasonic microphone:
How to Connect an Ultrasonic Sensor to an Arduino - Maker Pro
2019年4月25日 · Learn how to build an electronic tape measure using an HC-SR04 ultrasonic sensor and an Arduino Uno board.
Low-cost Hydrophone and Ultrasonic Transducer - Instructables
Low-cost Hydrophone and Ultrasonic Transducer: Do you want to record dolphins or whales speaking? Or build an underwater acoustic communication system? Ok, we're going to teach you ‘how to’.
Creating a ultrasonic sound generator - Arduino Forum
2020年10月20日 · I am trying to build a device that produces a specific tone of ultrasonic sound. What I want the device to do is to play the tone when the arduino receives a signal from a separate module. The tone will be in a range from 17kHz to 20kHz and is 100 ms duration, but I would like to play the tone repeatedly.
